IMPROVEMENT m DOOZ'HANGEIRS.

Specification forming part of Letters Patent No. 175,243. dated March 28, 1876; application filed January 26, 1876. v

To all whom it may concern:

Be it known that I, ROBERT L. GLENN, of St. Oharles, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Barn-Door Hangers, of which the following is a specification:

The present invention relates to that class of hangers which are to' b'e secured to the upper ends of sliding doors, and obviate friction central section of the hanger in position, and section of track.

shank or strap of the which is provided with holes 00, in the A represents the hanger,

ordinary manner, for fastening it to a door, F. It may be extended, as shown by dotted lines z, where greater strength is required. The top end of this strap is provided with a disk,

a rim, D, except at the bot- B, surrounded by tom the rim is cut away to allow the track H -to come in contact with a ring, G, and it has projecting inwardly an annular bearing, J. Inside of the rim D is placed an annular ring, G, and between the ring G and the bearing J are placed anti-friction rollers I, so as to travel freely round thebearing J. Over these rollers and ring is placed a cap, 0, which is fastened by means of a screw-bolt, E. The shank A is fastened to a door, F, in the ordinary manner, and the ring is placed on the track H and travels thereon. The shank or strap A on one side of the track, and-the cap 0 projecting over the opposite side, prevent the ring from getting out of place.

1 know that anti-friction rollers have been before used; I therefore confine myself to the following specific claim. p I claim and desire to secure by LettersPat:

rollers I, annular center J, shank A, case B c D, the cap 0 projecting down against the track H to keep the ring in place on the track, all substantially as settforth, for the purpose specified.
